Investigating the Effects of Flue Gas Injection, Hot Water Distribution, and Fill Distribution on Natural Draft Wet Cooling Tower Performance [PDF]

, 2020
Natural draft wet cooling towers (NDWCT) are a common method of heat removal in powerplants. This study employs a numerical cooling tower model developed by Eldredge, Benton & Hodgson (1997) to examine whether utilizing nonuniform water, fill profiles ...

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

INTEGRATION OF A MATHEMATICAL EXERGOECONOMIC OPTIMIZATION PROCEDURE WITH A PROCESS SIMULATOR: APPLICATION TO THE CGAM SYSTEM

Revista de Engenharia Térmica, 2005
In the present work a recent development and implementation of an integrated approach for mathematical exergoeconomic optimization of thermal systems is described. The proposed integrated approach is designed to exploit the computational power of a professional process simulator, so that the optimization procedure may disregard the variables associated

Optimizing end-labeled free-solution electrophoresis by increasing the hydrodynamic friction of the drag-tag

, 2009
We study the electrophoretic separation of polyelectrolytes of varying lengths by means of end-labeled free-solution electrophoresis (ELFSE). A coarse-grained molecular dynamics simulation model, using full electrostatic interactions and a mesoscopic ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

The characteristic analysis of the built-in vector atomic magnetometer in a nuclear magnetic resonance oscillator

AIP Advances, 2019
We analyze the amplitude-frequency, phase-frequency, signal amplification, linear range, and vector characteristics of the built-in vector atomic magnetometer operating at extreme off-resonance condition in a nuclear magnetic resonance oscillator, which ...

Fatigue Analysis of Actuators with Teflon Impregnated Coating—Challenges in Numerical Simulation

Actuators, 2021
Actuators are essential components for motion in machines, and warranty service lives are basic specifications of actuators. However, fatigue damage or wear of actuators are very complex and related to many design factors, such as materials properties ...

Sensitivity of the NEMO telescope to neutrinos from microquasars [PDF]

, 2006
We present the results of Monte Carlo simulation studies of the capability of the proposed NEMO telescope to detect TeV muon neutrinos from Galactic microquasars. In particular we determined the number of the detectable events from each known microquasar

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
